Interpolation of MOSFET table data in width, length, and temperature

Table-based transistor modeling techniques require a current table and a charge/capacitance table for each device geometry at each simulation temperature. Simple interpolation methods can be used to construct any current table from a small basis set of tables. A database of 32 current tables (two widths, four lengths, measured at four temperatures) is sufficient to span the space defined by these sample points. The technique provides an accurate rendering of the transistor current above threshold without the need for complex parameter optimization and without the need for an exhaustive database of current tables
